Improvement of holographic grating efficiency in Ag/AsGeSeS double layer

We have investigated the effect of Ag doping and the polarization dependence in Ag/As/sub 40/Ge/sub 10/Se/sub 15/S/sub 35/, and As/sub 40/Ge/sub 10/Se/sub 15/S/sub 35//Ag double layers, with respect to the holographic grating formation.
